Technical Field
The invention relates to the technical field of cable laying equipment, in particular to a cable lifting device and a processing method.
Background
When laying heavy type cables of high pressure such as 110kV, 220kV, 500kV in the tunnel, construction worker need promote the cable to the height of 1m ~ 2.5m, under construction condition and technical condition in the past, mainly adopt the mode of manpower promotion to the promotion of heavy type cable of high pressure, be equipped with two at least workers at every section distance along the cable promptly, arrange along the cable so and adopt people to lift the mode of shouldering and promote the cable to predetermined support layer, need to set up the scaffold of certain height at every section distance to higher-level cable, there are several shortcomings in this kind of mode:
firstly, the construction cost is high: the high-voltage cables laid in the common tunnel are long in length, large in section and heavy in unit length, and a large amount of labor is required by adopting a pure manpower lifting mode. For example, when a high-voltage heavy cable with the voltage class of 220kV, the conductor section of 1200mm2 and the length of 600 m is laid, the cable is lifted section by 40m, two lifting cables are arranged at intervals of 5m, at least 16 persons are needed for lifting the cable, and 121 scaffolds are needed to be built for the whole section of cable when the cable is required to be lifted to a higher-level bracket.
Secondly, the working efficiency is low: as mentioned above, a scaffold is required to be built every 5m, two workers are required to be built, the two workers transmit cables from low to high, each worker needs to bear a load of about 150kG, the maximum cable is lifted by 2m, 16 workers need to repeatedly bear the load for 15 times to lift the whole cable, the requirement on the physical quality of construction workers is high, and laying of the one-time cable (3 cables) needs to take a working day at least, and is time-consuming and labor-consuming.
Thirdly, the safety coefficient is low: when a manual lifting mode is adopted, heavy cables need to be manually lifted, and potential safety hazards in the construction process are high.
Fourthly, poor synchronism: because many people are needed to cooperate and carry simultaneously, the field needs commanders to continuously carry out field progress control, construction management is inconvenient, and the process is synchronous and is difficult to control.
